Hi,
I'm new to acoustics and I want to know if there is a formula regarding of comparing
recorded dB(decibels) from microphone that is from negative values to zero, around (-47dB that is almost quite) to 0dB that is almost the highest level with default (normal) hearing dB-s like dB on the restaurants around 60 dB.
To be clear is there a formula that convert this range (-47dB -0dB) to hearing dB (positive dB-s).
Thank you!
